  • Patent number: 10987231
    Abstract: A locking grip extraction tool has plier handles with jaws having sharp beveled edges for moving in a direction so that an axis perpendicular to the plane of movement is oriented at an acute angle to the handles; the axis intersecting the plane of jaw movement at a point midway between the jaws. A locking link coupled to the handles is adapted to releasably lock the jaws onto an orthopedic implant. A connection rod can be threaded into a hole in one of the handles near the jaws, so that a force applying tool such as a slap hammer can be connected to the rod to apply force to remove the implant. The rod is in alignment with the axis, which alignment makes it easier to remove the implant.

  • Patent number: 10112233
    Abstract: An adjustment system for a fastener pulling head is provided that includes a swivel adapter configured for engagement with a proximal end portion of a drawbolt body of the pulling head, the swivel adapter defining an internal bore. A cap screw is disposed within the internal bore of the swivel adapter and configured to threadably engage the drawbolt body, and a set screw is configured to engage and secure the swivel adapter within the drawbolt body. The set screw is tightened in order to install or remove the fastener pulling head from a power tool. Once installed on the power tool, the set screw is disengaged from the swivel adapter, the pulling head can be rotated, which causes the frame to move relative to the drawbolt body within the pulling head to adjust a jaw gripping force.

  • Patent number: 9964202
    Abstract: A maintenance tool for a planetary gear comprises a force generating device (101) comprising an actuator (102) for fastening to an end of a planet wheel pin of the planetary gear and for directing axial force to the planet wheel pin, and a body structure (104) for mechanically supporting a frame of the force generating device with respect to the planet carrier of the planetary gear so as to allow the actuator to move the planet wheel pin axially with respect to the planet carrier. In many cases, the maintenance tool enables removal of a planet wheel pin and installing, the same or another planet wheel pin at an operating site of the planetary gear. Thus, there is no need to move the planetary gear away from its operating site, e.g. a nacelle of a wind power plant, for maintenance work comprising removal of one or more planet wheel pins.

  • Patent number: 9956674
    Abstract: A replacement tool removes an old bushing or installs a new bushing in a driveshaft yoke. A fixture has a guide chamber facing a bushing bore and a first threaded passage. A traveler mounted in the fixture has a plunger received in the guide chamber and a socket that holds the bushing. The plunger has a second threaded passage aligned with the first passage and having a smaller diameter. A set screw can lock the bushing into the socket. A removal bolt with a shaft matching the second passage is inserted through both passages. Turning of the removal bolt retracts the traveler and extracts the bushing. The tool is reconfigured with an installation bolt in the first passage only. A push plug is placed in the guide chamber to transfer force from the installation bolt to the plunger during turning of the installation bolt to press fit a new bushing.

    Abstract: The CV joint removal tool's clamps surround an axle proximal to the CV joint to be separated from the axle. The tool clamps onto the axle and applies a constant axial force to separate the two CV joint components via the push plate and push rods. Removal of the entire axle assembly is negated, saving parts cost and labor costs. The tool does not require complete drive axle removal, as do other devices attempting the same function. The CV joint removal tool pushes the CV joint and the axle apart, further differentiating from previous methods and devices. The tool utilizes Newton's law of equal and opposite reactions. The key challenge that the CV joint removal tool overcomes is that when CV joints are installed, neither end of the drive axle is accessible.

    Abstract: A device to remove a metal servo horn in an efficient way by utilizing the lifting force to separate servo horn from a servo output shaft when screw is rotated counter-clockwise and hits against the concave of lower surface of upper front plate of the device. Clamping force provided by two fastening members combines the device and servo horn into one integrated unit to avoid the distortion of open end of the device when lifting force is greater than rigidity of the device. When a lifting force for removing the integrated unit is applied in direction opposite to installing direction of servo horn, it overcomes the friction between the inner splines of servo horn and the outer splines of servo output shaft then separates both splines. The removal of the servo horn from the servo output shaft is achieved.

  • Patent number: 8528177
    Abstract: A mandrel extraction tool includes an actuator assembly and a first mandrel interface arm operably associated with the actuator assembly and adapted to engage a first mandrel. The mandrel extraction tool further includes a second mandrel interface arm operably associated with the actuator assembly and adapted to engage a second mandrel, the second mandrel interface arm being slidingly coupled with the first mandrel interface arm, such that the first mandrel interface arm moves generally linearly with respect to second interface arm when the actuator assembly is actuated. A method for extracting a mandrel includes providing a mandrel extraction tool, engaging the mandrel extraction tool with a mandrel, and applying a force to the mandrel to linearly extract the mandrel from a first portion of a structure.

  • Publication number: 20130145591
    Abstract: A pressing disc for disassembling bearings includes three arc members each has a clamp portion and a through hole on each of two sides thereof. The three arc members are coupled with each other to allow any one through hole of any one arc member to communicate with the opposing through hole of the neighboring arc member to form a channel. The three clamp portions are connected with each other to form a clamp space. The pressing disc also has three penetrating rods respectively running through the channel. Each penetrating rod has one set of fastening member to push the arc members close to each other to shrink the clamp space. Thus a bearing placed in the clamp space can be firmly clamped through the three clamp portions from three pressing directions without slipping during disassembly.

  • Patent number: 8418363
    Abstract: A plunger installation tool that exerts a force on a plunger for a reciprocating pump to install the plunger into a pump cylinder opening. Maintenance of the pump typically includes repacking of the packing that surrounds the plunger and revalving of the pump's inlet and outlet valve. To allow repacking or revalving, the pump is disassembled and the plunger is removed. The plunger installation tool threads onto the pump cylinder opening to provide a reaction point for a threaded rod that is driven at one end by a driver and engages the plunger at an opposite end during installation to push the plunger into the cylinder opening without the use of hammers by personnel.

  • Patent number: 8371006
    Abstract: A system and method for extracting seized components is disclosed. The method further grasping a seized component with a gripping mechanism and securing the gripping mechanism to the seized component by turning a camlock mechanism. A force is applied to a power transfer mechanism that moves a threaded axis that is threaded through the power transfer mechanism. The method additionally includes attaching the threaded axis to the gripping mechanism, which extracts the seized component. To facilitate extraction, the method also includes generating vibrations by a vibration mechanism, which may include a vibration mechanism rotating a rotary plate about a shaft. The method may also include generating vibrations by a cam attached to the rotary plate contacting one or more spring-loaded hammers. The spring-loaded hammers may be capable of impacting a strike plate, generating vibrations.
